123 [This entry is a summary, not a precise list of changes.]
124
125 Added --csv option to enable processing of comma-separated
126 values inputs. When --csv is enabled, fields are separated
127 by commas, fields may be quoted with " double quotes, fields
128 may contain embedded newlines.
129
130 If no explicit separator argument is provided, split() uses
131 the setting of --csv to determine how fields are split.
132
133 Strings may now contain UTF-8 code points (not necessarily
134 characters). Functions that operate on characters, like
135 length, substr, index, match, etc., use UTF-8, so the length
136 of a string of 3 emojis is 3, not 12 as it would be if bytes
137 were counted.
138
139 Regular expressions are processed as UTF-8.
140
141 Unicode literals can be written as \u followed by one
142 to eight hexadecimal digits. These may appear in strings and
143 regular expressions.
